FIELD: radio engineering, communication.SUBSTANCE: system includes receiving stations (4) for receiving signals transmitted from the spacecraft (6) and a processing station (2) for receiving data from the receiving stations (4), where each receiving station (4) records, during a recording window (8), signals transmitted from the spacecraft (6) and transmits, to the processing station (2), data representing the recorded signals. The recording windows (8) associated with each of the receiving stations (4) are offset and/or have different size with respect to each other. The processing station (2) correlates the recorded signals to estimate the distance difference between the spacecraft (6) and each of a plurality of receiving stations and to estimate the spacecraft (6) position.EFFECT: avoiding the need to send a reference signal pattern, emission by the spacecraft of any trigger sequence and the need to adapt the spacecraft, and improved estimation of the position of the spacecraft.22 cl, 10 dwg, 1 tbl |
